Some chase the good weather. They plan everything according to convenience.

But others…well we don’t let cooler temps, mis-timed seasons, or mother nature dictate what we can or can’t do.

To us, we require more out of our gear to live life on our terms.
And that’s exactly why we need gear designed for maximum performance, such as the Highline Thermal Leggings.

  • More Warmth For Less Weight: To us, nothing is basic and nothing should be overlooked, so when we decided to design thermals we started by researching and testing a wide variety of fabric options, eventually landing on an ultra lightweight, 100% polyester, Japanese fabric that is lofted on the inside using a proprietary method to give you the most loft for the weight in its class.
  • Excellent Stretch With Faster Dry Times: The highline thermals offer great stretch and shape retention without the use of spandex - allowing less weight, faster dry times and more comfort next to skin.
  • Superior Temperature Regulation & Venting: When using thermals during the day or sleeping in them at night, a common problem is venting in target areas. We’ve added a vented crotch gusset to ensure warmth in the right areas and eliminate overheating in others. This allows you to extend your time in the thermals or sleep more comfortably through the night.
  • Ultralight Weight & Packability: These sub 4 ounce thermals take the edge off of those cold mornings, late nights or brisk winter trips all while packing down to nothing in your pack.

Whether you're embarking on a cold-weather hike, seeking a more comfortable sleeping set, or simply braving chilly mornings, our Highline Thermal Leggings will keep you warm and comfortable without weighing you down.

    Highline Thermal Leggings

    These leggings are the best base layer I've ever encountered. Although I am an avid backpacker, I also work outside doing highway work in all theweather conditions offered in Ohio. At 53 years old, I've worn every fabric from cotton to denim to heavy coveralls. I now own many products that Outdoor Vitals offer. Their highly effective and ultralight gear transfers comfortably from trail to highway. The leggings are loose fitting and very warm and comfortable.
    Many thanks to the O.V. crew for their contributions to affordable, effective gear.

    The best for ultralight warmth

    Ordered one pair and loved them so much, I ordered another. Seriously, I could live in these leggings! They are warm even with a cold wind. They don't have pockets so I wear a hiking skirt on top of them and it works!

    I’ve only slept in these at home so far but they are ridiculously comfortable and breathable.

    Another excellent product from OV.

    When I got these I couldn’t believe how light they were. So I tried them out on a wintry day in Michigan at the dog park!. Wow! Are they ever warm! But what is really interesting is that they don’t feel too hot or bulky under clothes inside like regular long underwear.
    One of my new favorite pieces of gear!
